wagers;

To all whom it may concern:

lie it known that I. Jaeon Fnnnnil, citizen of the United States, and resident of the borough ol .\Iauhattan, city of New York. in the county of New York and State of New York, have invented certain new and useful improvements in Type-Whiting .Machines. ot whirl] the following is a specificalion.

.\l v invention relates to paper feeding met-lianisms lor typewrit'ing machines and more especially to what are commonly tcrmcd leading edge stop devices.

()ne of the main objects of my invention is to provide in conjunction with the paper Specification of Letters Patent.

Application filed March 27, 1909.

1 key will itself be t maintain the leading edge feed mechanism at the rear of the platen a leading end or edge stop mechanism not wholly under control of the paper feed release mechanism. but adapted to cooperate therewith so that the paper feeding devices may be released from (it): *ative position and restored to operative position without bringing into action the leading end stop devices, and also to provide a construction such that when the paper 'lccding mechanism has been the leading end stop members may he indepcndently brought into operative position then automatically rcleased by the operation of'the means employed for restoring the paper feeding de vices to their normal positions.

Other objects will appear hereinafter.

To the above and other ends the invention ronsists in the features of construction. combinations of devircs and arrangements of parts, hereinafter described and particularly pointed out in the claims.

In leading edge stop devices as heretofore constructed it has been customary to connect the leading edge stops with the feed roll releasing mechanism so that said stops will hebrought into operation by the release key. My improvements contemplate the provision of a lteyseparatc from the usual release key and operative indtaiendently of said release key whereby the leading edge stops are tive position into operative position a ainst the platen. Preferably this special key is operated after the release key has beenoperated and locket'l. to retain iu'inoperative position the paper feeding devices controlled by said release key and which are normally operative. Vi'hcn so operated this speciztll those in which they some of the parts shown Patented Oct. 12, 1909. Serial No. 486,210.

held by a lock so as to stops in operative position against the platen. When the release key is unlocked and returned to normal position, together with the paper feeding devices which it controls, the special key and the leading edge stops will at the same time be automatically unlocked from operative position and will be restored'to the normal inoperative position. If the special key be operated at times when the release key is in normal position, then the lock or latch for said special key will not be broughtinto action, and consequently at such times the leading edge stops will not be locked against the. platen but will only be retained thereagainst as long as the special key'is pressed by the operator.

My invention is shown applied-to a. Monarch typewriting machine but may be adapted to other styles of writing machines. In the accompanying drawings, Figure l is a fragmcntay bottom plan view of the platen carrier and platen of a Monarch t pewriting machine einliodying one forn'f'o my invention. Fig. 2 is a vertical sectional view taken on a plane represented by vthe dotted line -r-.1' in Fig. l and'lookin in the direction of the arrows at. said ine, Fig. 2, however, showing the platen carrier turned over in its normal position. Fig. 3 is a fragmentary end view of the platen and parts of the paper feedingmechanism and leading edge stop devices, said parts being shown in abnormal osition. Fig. i is a view corresponding'wlth Fig. 3 but showing some of the parts in ditlerent relations from appear in said Fig. 3. Fig. is a fragmentary rear elevation show-. ing parts of the paper, feeding,.mechanism 95 and leading edge stop devices, the left-hand end bar of the platen carrier being shown in section. Fig. 6 is a fragmentary perspective view of the special key for the leading edge stop devices and ot' the parts which cooperate to provide a lock f or said key. Fig. 7 is an end view of the platen and platen carrier of a. Monarch'typewriting machine embodying a modified construction of my invention, the left-hand platen finger wheel hein sectioned awa Fi s. 8 and S) are 7 )3 views corresponding to Fig. 7 but omitting in said Fig. 7 and showing other parts in different relations.

The form of the invention illustrated in Figs. 1 to 6 inclusive will first be described. The platen carrier or carriage comprises'a back bar 1 and side or end bars Band 3,

3 said back bar being grooved at its top and bottom to cooperate with the usual antifriction balls (not shown). The platen 4 is mounted on an axle 5 which bears in the end bars and is provided at its ends with finger wheels 6, one of which is shown. A line spacing wheel 7, operatively connected with the platen, is adapted to cooperate with other line spacingdevices (not shown) to turn the platen step-by-step for line spacing.

,carries the sections 16 of the secondary feed roller. Normally the main and secondary feed rollers are respectively maintained in contact with the platen or the paper thereon by springs 17 and 18. The main feed roller cotiperates with the platen at the rear of the under side thereof, the secondary feed roller cooperates with the platen at its f front face of. the platen. 35

under side forward of the main feed roller,

awhile both feed rollers are between the pomt. at'the. rear where the work sheet is introduced and the printing point on the A rock shaft 19 hearing in the ends of the platen carrier is provided with lugs 20 which engage with the beveled ends of pins 21 onthe arms 9 (when the rock shaft 19 is turned forward) and overcome the springs 17 and 18, swinging the arms 9 and 10 downward and rearward and releasing the main and secondary feed rollers. The release of the secondary feed roller isaccomplished by extensions 9 on the arms 9, said extensions engaging with the arms 10 to'niove said arms. A paper apron or deflector 22 is pivotally supported on the rock shaft 19 and its forward end portion is normally pressed against the platen by springs 23 secured to the arms 10. Thesect1ons of the main and secondary feed rollers protrude through openings in said paper apron to contact with the platen or the paperthereon. When the rockshaft 19 is turned forward to release the feed-rollers the downward movement of the arms 10 causes the pressure of the springs 28 on thepaper apron to relax. The parts thus far described are common to the Monarch machine. 5

The releaserock shaft 19 may be turned or operated by any desired means, that shown in the drawing being the invention of Edwin E. Barney and comprising devices for locking the feed rollers when released. Said means comprise a crank arm 24: secured to the lever '28.

end of the rock shaft outside the end bar by a screw 25. Nornmlly a. nose 24- on said crank arm is maintained against :1 laterally projecting stop pin 26 on the end bar 2 by a spring 27 coiled around the opposite end of the rock shaft 15) and having one end soc'urcd thereto and the other end secured to the end bar 3. The normal positions of the rock shaft, feed rollers-and paper apron are shown in Fig. releasing lever 38 is pivotally connected at. 29 to the crank arm 21 and at 30 to a guide arm 31 which in turn is pivoted on the usual paper linger rod 212. The upper or free end of the release lever 18 terminates in a finger piece 28 which is turned or twisted at right angles to the body of the lever and which is adapted to contact with the rear or upper edge of the guide arm 31 to limit the forward movement of the The levers 2S and 31 are tog le elements which normally are angularly isposed as in Fig. 2; but when the finger piece 28 is pulled forward the toggle elements are straightened, as shown in Fig. 3, so that the crank arm 24 and rock shaft. 19 which have been turned forward by said finger piece will be maintained in the abnormal positions shown in Fig. 3, thus locking the two sets of feed rollers in released "or inoperative positions.

The leading edge stop devicesshown in the ]')rcsent case comprise supporting arms or T ln'ackcts 33 which are secured by the screws 11 and 12 to the outer faces of the lugs 8 and extend downward below said lugs, inclining forward somewhat also. A rock shaft 34 extends from one arm 33 to the other ,below the arms 10 and is pi'votally supported on said arms Disposed at intervals length wise of said rock shaft and suitably secured thereto are leading edge stop members 35, four being shown. These stop members-normally extend forward and slightly downward from the rock shaft and terminate in angula'rly disposed-portions 86 which extend upward and slightly forward,- being somewhat pointed at their ends. These angular portions 36 serve as leading edge stops proper. A coiled dra w spring 37 is conn'ccted at its lower end to a pin 38 or other device secured to the rock shaft 31and extending rearward therefrom; The upper end of the spring 37 is hooked around therock shaft 19. As will be understood from Fig. 2 the spring 37 tends constantly to-turn the rockshaft 34 in the direction of the arrow and to force the stops 36 away from the platen. The apron is formed with slots39 through which the stops 36 may move into contact with the platen and away therefrom.

Norn'ially the action of the spring 37 is limited and the stopsBGare held. away from the platen in the position shown in Fig. 2 by an arm 40 which is secured by a screw 4-] to the left-hand end ofthe rock shaft34.

shaft 34;,t-he latter being outside the end bar 2. said arm extentlin a npward and being caused to contact with thc rear side otthc stop pin it; by said sprinn' 37. T116311}! it) on the rock shaft 34 may be formed with a hole ha ring a straight side or sides which fits over the: end of the rock I reduced for the purpose and the reduced portion having a corresponding straight side or sides, the con struction being such that when the screw it tightened the arm 40 is held from displacement and.inaintamed at all times in a fixed i-elati'o rwiththe rock shaft -H. .\s be t shown in Figs. 5 and (3 the arm 40 is pro- Vided near its upper end with a laterally cx tending finger piece 42. When this fingcr piece is pushed rearward the spring 37 will beoi'ei'coine and the leading: cdg'e stops 3t; forced into contact with the platen or the paper thereon. it will be apparent that thc operation of the release arm 28 to release the feed rolls is independent of and will not afl'ect the leading edge stops: and that said stops maybe moved into and out oi operation by the finger piece 42 without affecting the feed rollers. It will also'be understood that with the mechanism asfithns t'ar described .the leading edge stops when forced toward the platen will rccede therefrom as soon as pressure on the finger piece 4-2 is removed.

. In order to maintain the leading edge stops in operative position I provide locking de- V1CGS '\\'ll1('ll preferably cooperate with the feed roller releasing mechanism in such a Way that said locking devices will be brought.

into action when the teed rollers are locked away from the platen as shown in Fig. 3 and when with the feed rollcrs so locked away the finger piece is pushed rearward.

The locking devices for the leading edge stops comprise a locking" pin or dctcnt 43 which as best shown in Figs. 5 and (3 is rertically d sposed and supported in cars 4-4 and 45 extending laterally inward from the arm 40. The upper lug or ear 44 is or may beifoi'ni'ed by simply bending ovcr the upper end portion of thc arm 40 until it is substantially horizontal. The lower log or car 4:") is or may be provided bya lip formed at thc front edge of the arm -l-t) and bent laterally inward. The lower end portion of this l p which iscnt away or severed from the trout edge of the arnr40 is then bent. horizontally rearward sothat it-is at right angles to thc forined with bt-aai'ing; openings which receive the locking pin 43 and through which the locking pin may be slid up and down. A

collar or flange 4-6. suitably secured to the locking pin between the lugs -14 and 45.

' limits the up and down movements of said which contacts with and slides along the Said flange 46 has a straight face i lifddl inner face of the arm 40. the construction being such that the locking pin is prcvcntcd t'rom rotatin; on its own' axis. wirc spring 47 is coiled around thc locking; pin and confined between. the flange lo and thc under iace of the lug ll. Normally said spring maintains the tiangc in contact with the lower log 45. The lower end portion ot the locking pin 43 below the lu 4 is curved or beveled at its t'ront face as indicated at 48 and a short oppositely incliiicd bt-vcl l9 formed at the lower lip ol said locking pin, as is best shown in Figs. 2. ii and t. The lower end portion of thc ltlth" ing pin is adapted to cooperate with a uosc or lug 50 which may l i and preferably is made integral with the crank arm 2t and is otl'sct laterally outward therefrom. The up per cdge 51 of the nose 50 is straight and normally ii'iclincs rearward and slightly up ward as shown in Fig. The lower cdp'c .32 ol the nose 50 is orniay bc curred downward and forward from its junction with the up per edge 5 Normally as shown in Fig. 2 the nose 5!) and the locking pin 43 are sc iiaratcd by a considerable space. (\"hcn the linger piece 28 is pulled forward and the 't'ccd I'Olltl's are locked in lf'tlQztStlCl position. the nos-tso will be brought closer to thc lowcr t the locking, pin 43 but not quitc int with it. if now the arm it) be swung rcar ward. preferably by prcssurc on tho finger picce the bevclcd tip 49 ot' the locking pin will contact with the upper cdg' 1 of thc nose 5() at. an early stagc in tho rcarward movement oi the arm 40. .\s the rcarward swing of the arm 40 is continued a t'tcr such contact the edge 51 will coiipc'ratc with the bevclcd tip 19 to force or cam the locking" pin 4 upward in its bearings ii 'ainsl the pressure of the spring 47. compressing aid spring until the rear cnd ot the edge 51 is rcachcd. 'llhcreupon the spring 4? acting; against the flange it will force the locking pin '2; do\\*n\\'ard behind thc nosc St). the beveled or curved 'lacc it slidil'ig down over thc cd 'c 52. It will, be apparent that by this operation the arm 4.0 will be lOth'ttl by the nose 50 in rearward position as shown in Fig. IL-which figure it will be noted is a view showing thc parts at the side opposite trom that in which they are shown in Fig. 2. The result will be that when pressure on tho finger piccc 42 is removed the arm it) will ho held troni swinging back to normal position by reason of the engagement between the locking elements l3 and 5t), and consequently. the leading edge stops $36 will be held locked in operative position against the platen as shown in Fig. 3. Both hands of the operator are therefore free to insert the invoice or other \VOih sheet (indicated by the dotted line ini ig. 3) into the machine over the usual paper table (not. shown p o'l o contact of the work sheet; into contact with the leading edge stops 3G. 'lhereafter the finger piece 28* may be pushed rearward in the direction of the arrow' in Fig. 4, restoring the feed rollers to operative position, the main 53 and pressing it against-the platen as indicated in Fig. 4. During the return of the 7 feed rollers .to operative position the nose O will swing downward, the edge 52 sliding over-the beveled edge 4-8 of the lockin pin. At the time that the. feed roller 14 c am s the worksheet the tip of thenose 50 will lie near the lower tip of the, locking pin 43 as shown in Fig. it but will still be in en agement with said locking pin sufficient y to hold the arm in looking position and to maintaiuthe stops 36 in the path of the leading edge of the work sheet. As a result of this construction the stops 36 will remain in control; of the paper until it has been clamped against the platen by the feed'roller 14-. A slight additional movement of the finger piece in, the direction of the arrow in Fig. '4 from the F ig. 4 position-will swing the nose downward out of engagement with the locking pin 43 and will thereupon permit the spring 37 to restore the leading edge stop devices to normal position as I shown in Fig. 2. It'will be apparent that by this const-ri'ietion the locking devices includ ing the locking pin 43 and nose 50 will-be brought into action only when the feed rollers have been previously released and thatwithout such release of the feed rollers the arm pa per stops moved against and away from the platenv without locking said stops in opa. ei'ative position.

In the modification illustrated in Figs'T,

8 and 9 the operating arm 40 and its eo-' operating latch arereplaced by other devices. These other devicescomprhse a crank arm 54 which iS';SBCLl1e(l to the left-hand end of the rock shaft 34 by a'screw '55 and extends rearward therefrom. Pivotally con nected to the free end of said crank arm at 56h, a-vertically disposed bar or arm 57 which terminates at the top in a horizontally disposed finger piece The bar 57 is in part. guided and controlled by a guide arm 59 with which the bar57 is pivotally co nnectcd attit). The guide arm 59 is pivoted on a screw (51 which is supported on the end bar 2, the guide armextending rearward from the bar 57. A stop pin 62, extending to co-act with the rear edge of the operating vbar 57 as shown in Fig.7. This figure. illus-' lralestht. normal positioniof the parts. It \\'Ill be apparent that the. draw spring 57 tends constantly to turn the crank arm 5+ away from said arm 57.

E 111 normal position separated from the platen. feed roller contacting with the work sheet When pressure is applied to the finger piece 58 the operating bar or arm 57 will be bodily lowered and the guide arm 59 and crank arm 54 turned slightly downward, the movement of the crank arm causing the stops 36' to swing upward into contact. with the platen or the paper thereon, as shown in Fig. 8. It

will be understood from this figure that during the downward movement of the arm 57 and the guide arm 59 the stop pin (32 swings As in the former construction it will be seen that the leading edge stops may be operated independently of the feed roller controlling devices, and that in the absence of a lock or latch the operating arm 57 would move upward when pressure is removed and the steps 36 would swing down away from the platen. The lock in the'presont instance comprises'cowa'rd from aprojection or ear 68 on the 40 may be swung back and forth and the the crank arm 24. of the first construction with the exception that the new or projection 50 is replaced by the car (58 and nose 67. Normally the nose ($7 is forward of the path which the nose 06 takes when the operating bar 57 is moved downward and upward as will be understood from Fig. 7 \Vhen, however, the finger piece 28 is pulled forward to release the feed rollersand lock them in the inoperative position, the nose (37 will be swung rearward into the path of the nose (36. (onsequently if after the release and looking away of the feed rollers, the bar or arm 57 is pressed downward, the locking nose 66 will first ride over the locking nose (37 which latit to move forward and bring the nose G6 under the nose 67 so as to lock the parts .as shown in'F i 8 and prevent the return to normal positlon of the operating bar or key 57 and the leading edge stops 36.

After the work sheet has been adjusted against the stops 30 the feed rollers and the stops 30 maybe released and restored to normal position by pushing rearward the linger piece 28, the controlling devices for the feed rollers tnpei'at-ing.automatirallv to permit the return of the leading edge stop devices at this time. During the first part of the return movement or until the feed rollers return to clamping engagement with the platen or the paper thereon the leading edge stop devices .will remain locked in operative or abnormal position. This will be understood from Fig. 5) wherein the parts are shown in the positions they will occupy ust after the feed rollers have returned into coiiperation with the platen. It will be noted that the locking nose (37 has moved forward over the nose till a considerable distance from the position shown in l ig. H, but that said nose (37 still controls and holds locked the nose (3t; and the parts connected therewith. Consequently the stops 36 will remain in operative position until after the feed roller 14 has clamped the invoice or work sheet 53. When, however, the finger piece 28 is pushed rearward a short distance beyond the Fig. 9 position. the locking noses will disengage and the spring- 3-37 will thereupon operate to restore the leading edge step devices to the normal positions-shown in ig. 7.

Both described constructions provide means for accurately positioning and clamping work sheets as they are introduced into the machine and these means, as is well understood, may be advantageously employed in bill-and-charge, condensed record work and other styles of con'nnercial t ypewriting or billing. In the present case in both formsof the invention a key is provided for controlling the paper stop devices. which key is separate from the release key or key for controlling the releasing? and locking otl' ot' the feed roller or re] (ll-s. The stop controlling key is arranged in proximity to the release key and is'operated by the same hand of the operator as is the release key and may be operated during the same or releasing operation which, of course, in many instances is a great convenience. It will be observed that the feed rollers and the paper stop or stops are movable relatively to the platen through openings in the curved paper deflector or apron the l eedrollers normally protruding through the deflector and cooperating or contacting with the platen or the paper thereon, while the paper stops are normally inoperative; that the deflector is spring pressed toward the platen and when the feed rollers are released pressure on the deflector is relaxed; that the main and secondary feed rollers are spaced apart ciremnferentia-lly of the platen and the paper stops are arranged between said feed rollers: that the main teed roller is anranged at the introductory side ol the platen and in advance of the printing point. that is, the main teed roller is so situated with respect to the printing point that when paper is introdiured into the machine it must pass the feed roller before reaching the printing point; that in this 0ll t3 the secondary feed roller and the leading edge stops are also arranged in advance of the printing point, the printing point in the pres ent instance, of course, being at, the front face of the platen, the Monarch typewriter being as is well known, a front-strike machine; that with the platen. the paper controlling devices such as a feed or pressure roller or rollers and means for locking said devices in abnormal position, i combine a paper stop such as a leading edge stop, and separate means for locking said paper stop in abnormal position; that in the present instance such locking of said paper stop is dependent on the prior locking of said pa per controlling devices; that the. paper controlling devices are locked away from the platen or in inoperative position while the paper stop is locked in contact with the platen or in. operative position; that the provision of separate means for moving theleading edge or paper stop or stops and lock ing it or them, which means is separate from and operative independently of the means. for moving the teed roller or rollers and locking it or them, is a great convenience in many kinds of work; that in the present, instance the paper stop and the feed roller or the paper controllingdevices are releasable, at a single operation. the feed roller preferably returningto Opt .ative position in advance of the release of the paper stop; that this single operation in the present. instance is caused by actuating the release key of the machine; that the lock for the leading edge or paper stop comprises in the pre ent instance. two parts one of said parts being controlled by the paper controlling devices or feed roller devices and being in the nat ur. of an abutment which normally is in inoperative position but is automatically movable by the release key to a position where it will cooperate with the other part of the two-part lock: and thattlie other part of said two-part lock is a. spring-pressed detaent which may be a locking pin or nose or the like, said detent being connected with the key controlled paper stop devices and being automatically movable thereby into cooperation with said abutment.

The details of construction may be greatl y varied without departii'lg from the spirit of my invention, and it will be understood that any suitable form of paper feed mechanism and any suitable construction of releasing and locking mechanism: may he used lltl Hill

Ill-5 llt] in conjunction with the paper feeding mech anism, and the means for casting on and locking the leading edge steps may likewise be greatly varied without departing from the principles of my invention.
